TECHNICAL FIELD

The present invention relates to a compound that has a TrkA inhibitory activity and is useful in the treatment and/or prevention of TrkA mediated disorders, or a pharmaceutically acceptable salt thereof, and a pharmaceutical composition comprising the same.

BACKGROUND ART

The tropomyosin receptor kinase (Trk) is a family of receptor tyrosine kinases and has a function as a receptor of neurotrophin (NT). Three major subtypes of Trk receptors are TrkA high-affinity receptor for nerve growth factor (NGF), TrkB high-affinity receptor for brain-derived neutrophic factor (BDNF) and NT-4/5, and TrkC high-affinity receptor for NT-3. All receptors involve in various physiological function in vivo. TrkA is mainly expressed in peripheral and central nerves, and involves in neuronal development and differentiation, and maintenance of neuronal functions. The gene mutation in TrkA is associated with painless anhidrosis in human (Patent Documents 1, 2 and Non-patent Documents 1 to 3). The activation of NGF-TrkA signal produces hypralgesia (Non-patent Documents 4 to 6). Clinical and non-clinical researches regarding anti-NGF antibodies and non-clinical researches regarding Trk inhibitors reveal the involvement of NGF-TrkA signal or NT-Trk signal in the pain of osteoarthritis, rheumatoid arthritis, bone fracture, interstitial cystitis, chronic pancreatitis, prostatitis and the like in addition to nociceptive pain such as chronic low back pain, neuropathic pain such as diabetic peripheral neuropathic pain, acute pain such as postoperative pain and chronic pain such as pelvic pain and cancer pain (Patent Documents 1, 2 and Non-patent documents 7, 8).

Trk receptors are also expressed in several types of cancer cells such as neuroblastoma, prostate cancer, lung cancer, breast cancer, gastric cancer and pancreatic cancer, and involve in the proliferation and migration of cancer cells. The fusion protein combined with TrkA kinase domain causes the proliferation of lung cancer cells. Trk inhibitor is shown to suppress the proliferation and metastasis of cancer cells in animal model. (Patent Document 1 and Non-patent Documents 9 to 12). Furthermore, Trk receptors are expressed in mast cells, eosinophils, immunocompetent cells such as T and B cells and keratinocytes, and NGF-trkA signal or NT-Trk signal involves in inflammatory bowel diseases such as ulcerative colitis and Crohn's disease, allergic diseases such as asthma and rhinitis, and skin diseases such as psoriasis, atopic dermatitis and pruritus (Patent Documents 1, 2). In addition, the inhibition of NGF-TrkA signal improves the overactive bladder (Patent Document 1). NT-Trk signal also involves in Sjogren's syndrome (Patent Document 1) and endometriosis (Patent Document 1). TrkA receptor plays a critical role in the infection process of the parasitic infection of Trypanosoma cruzi (Chagas disease) (Patent Document 1). Therefore, the compounds having an inhibitory activity for TrkA will be effective for various diseases including nociceptive pain, neuropathic pain, cancer, inflammatory diseases, allergic diseases and dermatological diseases.

The compounds that have an inhibitory activity for TrkA are disclosed in Patent Documents 1 to 18 and Non-patent Documents 6, 13 to 14. However, the compounds related to the present invention aren't indicated and suggested in any documents.

The compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) are not limited to specific isomers but include all possible isomers (e.g., keto-enol isomers, imine-enamine isomers, diastereoisomers, enantiomers, or rotamers), racemates or mixtures thereof.

One or more hydrogen, carbon and/or other atom(s) in the compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) may be replaced with isotopes of hydrogen, carbon and/or other atoms respectively. Examples of isotopes include hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, iodine and chlorine, such as ²H, ³H, ¹¹C, ¹³C, ¹⁴C, ¹⁵N, 18O, ¹⁷O, ³¹P, ³², ³⁵S, ¹⁸F, ¹²³I and ³⁶Cl respectively. The compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) include the compounds replaced with these isotopes. The compounds replaced with the above isotopes are useful as medicines and include all of radiolabeled compounds of the compound of Formula (I), Formula (I′), Formula (I″) or Formula (I′″). A “method of radiolabeling” in the manufacture of the “radiolabeled compounds” is encompassed by the present invention, and the “radiolabeled compounds” are useful for studies on metabolized drug pharmacokinetics, studies on binding assay and/or diagnostic tools.

A radiolabeled compound of the compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) can be prepared using well-known methods in this field of the invention. For example, a tritium-labeled compound of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) can be prepared by introducing a tritium to a certain compound of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) through a catalytic dehalogenation reaction using a tritium. This method comprises reacting an appropriately-halogenated precursor of the compound of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) with tritium gas in the presence of an appropriate catalyst, such as Pd/C, and in the presence or absent of a base. The other appropriate method of preparing a tritium-labeled compound can be referred to “Isotopes in the Physical and Biomedical Sciences, Vol. 1, Labeled Compounds (Part A), Chapter 6 (1987)”. A 14C-labeled compound can be prepared by using a raw material having 14C.

The pharmaceutically acceptable salts of the compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) include, for example, salts with alkaline metal (e.g., lithium, sodium, or potassium), alkaline earth metal (e.g., calcium or barium), magnesium, transition metal (e.g., zinc or iron), ammonia, organic bases (e.g., trimethylamine, triethylamine, dicyclohexylamine, ethanolamine, diethanolamine, triethanolamine, meglumine, diethanolamine, ethylenediamine, pyridine, picoline, or quinoline), amino acids, or salts with inorganic acids (e.g., hydrochloric acid, sulfuric acid, nitric acid, carbonic acid, hydrobromic acid, phosphoric acid, or hydroiodic acid) or organic acids (e.g., formic acid, acetic acid, propionic acid, trifluoroacetic acid, citric acid, lactic acid, tartaric acid, oxalic acid, maleic acid, fumaric acid, mandelic acid, glutaric acid, malic acid, benzoic acid, phthalic acid, ascorbic acid, benzenesulfonic acid, p-toluenesulfonic acid, methanesulfonic acid, or ethanesulfonic acid). Especially, salts with hydrochloric acid, sulfuric acid, phosphoric acid, tartaric acid, methanesulfonic acid and the like are included. These salts can be formed by the usual methods.

The compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) or pharmaceutically acceptable salts thereof may form solvates (e.g., hydrates), co-crystal and/or crystal polymorphs. The present invention encompasses those various solvates, co-crystal and crystal polymorphs. “Solvates” may be those wherein any numbers of solvent molecules (e.g., water molecules) are coordinated with the compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″). When the compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) or pharmaceutically acceptable salts thereof are allowed to stand in the atmosphere, the compounds may absorb water, resulting in attachment of adsorbed water or formation of hydrates. Recrystallization of the compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) or pharmaceutically acceptable salts thereof may produce crystal polymorphs. “Co-crystal” means that a compound of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) or a salt thereof and a counter-molecule exist in the same crystal lattice, and it can be formed with any number of counter-molecules.

The compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) of the present invention or pharmaceutically acceptable salts thereof may form prodrugs. The present invention also encompasses such various prodrugs. Prodrugs are derivatives of the compounds of the present invention that have chemically or metabolically degradable groups, and compounds that are converted to the pharmaceutically active compounds of the present invention through solvolysis or under physiological conditions in vivo. Prodrugs include compounds that are converted to the compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) through enzymatic oxidation, reduction, hydrolysis or the like under physiological conditions in vivo, compounds that are converted to the compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) through hydrolysis by gastric acid etc., and the like. Methods for selecting and preparing suitable prodrug derivatives are described in, for example, “Design of Prodrugs, Elsevier, Amsrdam, 1985”. Prodrugs themselves may have some activity.

When the compounds of Formula (I), Formula (I′), Formula (I″) or Formula (I′″) or pharmaceutically acceptable salts thereof have hydroxyl group(s), prodrugs include acyloxy derivatives and sulfonyloxy derivatives that are prepared by, for example, reacting compounds having hydroxyl group(s) with suitable acyl halide, suitable acid anhydride, suitable sulfonyl chloride, suitable sulfonyl anhydride and mixed anhydride, or with a condensing agent. For example, they include CH₃COO⁻, C₂H₅COO⁻, tert-BuCOO—, C₁₅H₃₁COO⁻, PhCOO⁻, (m-NaOOCPh)COO⁻, NaOOCCH₂CH₂COO⁻, CH₃CH(NH₂)COO⁻, CH₂N(CH₃)₂COO⁻, CH₃SO₃ ⁻, CH₃CH₂SO₃ ⁻, CF₃SO₃ ⁻, CH₂FSO₃ ⁻, CF₃CH₂SO₃ ⁻, p-CH₃O-PhSO₃ ⁻, PhSO₃O₃ ⁻ and p-CH₃PhSO₃ ⁻.

General procedures for the synthesis of the compounds of the present invention are described below. Starting materials and reaction reagents used in such synthesis are commercially available or can be synthesized according to methods well known in the art using compounds commercially available. Further, extraction, purification and the like may be performed in accordance with the methods carried out in the art.

In the following all steps, when a substituent which impedes a reaction, e.g. hydroxy, mercapto, amino, formyl, carbonyl, carboxy, is possessed, the substituent is protected by the method described in Protective Groups in organic Synthesis, and Theodora W Greene (John Wiley & Sons, hereinafter referred to as literature A) in advance, and the protecting group may be removed at a desirable stage. In addition, in the all steps, an order of steps to be implemented may be appropriately changed, and each intermediate may be isolated, and used in a next step. All of reaction time, reaction temperature, solvents, reagents, protecting groups, etc. are mere exemplification and not limited as long as they do not cause an adverse effect on a reaction.

Test Example 1 The Growth Inhibition Assay using TF-1 Cells

To produce the stable cells expressing four types of NT receptors (TrkA, TrkB, TrkC and p75) highly and simultaneously, each human NT receptor gene was transfected by a retrovirus vector into human erythroleukemic cell line TF-1 cells (ATCC Number:CRL-2003). The inhibition assay against NGF, BDNF and NT-3 were done in TF-1 cells expressing TrkA+p75, TrkB+p75 and TrkC+p75, respectively. Two hundred nL per well of each compound (final concentration: 20 μmol/L-1 nmol/L) dissolved in DMSO was applied in a white 384 well flat-bottom plate. The cells were suspended in RPMI-1640 medium containing 10% fetal bovine serum and seeded in each well at 400 cells for the TF1 cells expressing TrkA and p75 or TrkC and p′75, and 800 cells for the TF cells expressing TrkB and p75. Forty μL of human NGF (final concentration: 4 ng/mL), human BDNF (final concentration: 8 ng/mL) or human NT-3 (final concentration: 8 ng/mL) was added in each well and the plate was incubated for 3 days. Then, twenty μL of CellTiter-Glo reagent for CellTiter-Glo Luminescent Cell Viability Assay (manufactured by Promega) was added in each well and chemiluminescence was measured by a microplate reader to evaluate the growth of TF-1 cells. Luminescence value in the well incubated with or without each growth factor is 0% or 100% inhibition, respectively. The inhibitory activity of each compound was calculated by the following formula.

Inhibition (%)=(1-(luminescence value with compound−luminescence value of 100% inhibitory activity)/(luminescence value of 0% inhibitory activity−luminescence value of 100% inhibitory activity))×100

The 50% inhibitory concentration (IC50) was determined by the logistic regression using the inhibition data in 10 points of 3-fold dilution series at a compound concentration range of 1 μmol/L to 0.05 nmol/L.

Test Example 2 Human TrkA Inhibition Assay

Seven point five μL per well of human TrkA (PV3144, Lifetechnologies, final concentration: 1 nmol/L) suspended in the assay buffer (100 mmol/L 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES), 10 mmol/L magnesium chloride, 0.003 vol % Brij-35, 0.004 vol % Tween20 and 1 mmol/L dithiothreitol (DTT)) was applied in a 384 well plate and the plate was pre-incubated for 15 min at room temperature with 0.4 μL of each compound (final concentration: 200 μmol/L-0.1 nM) dissolved in DMSO. Then, fluorescent substrate (FL-peptide 27, 760424, PerkinElmer, final concentration: 1.5 μmol/L) and ATP (final concentration 500 μmol/L) dissolved in the assay buffer was added in each well. After the incubation of 120 min at 37° C., fifteen μL of termination buffer (100 mmol/L HEPES, 40 mmol/L ethylenediaminetetraacetic acid (EDTA), 10 mmol/L magnesium chloride, 0.003 vol % Brij-35, 0.004 vol % Tween20, 1 mmol/L DTT and 0.16 vol % Coating Reagent 3) was added in each well to stop the enzyme reaction. Fluorescent intensities (FI) of phosphorylated and non-phosphorylated fluorescent substrates were measured by LabChip EZReader II (Caliper LifeSciences, Inc.), and conversion ratio (CR) was calculated by the following formula-1. The CR in the well applied with DMSO alone was used as a negative control and the CR in the well without applying TrkA was used as a positive control. The inhibitory effect of each compound on TrkA phosphorylation was calculated by the following formula-2.

CR (%)=(FI of phosphorylated substrate/(FI of phosphorylated substrate+FI of non-phosphorylated substrate))×100   (Formula-1)

Phosphorylation inhibition (%)=(1-(CR with compound treatment−CR of positive control)/(CR of negative control−CR of positive control))×100   (Formula-2)

IC50 values (nmol/L) were determined by the logistic regression using the inhibition data in 10 points of 3-fold dilution series at a compound concentration range of 2 μmol/L to 0.1 nmol/L, or 15 points of 3-fold dilution series at the range of 200 μmol/L to 0.04 nmol/L.
